Ensure continuous motor operation. Protect from water and corrosion during downtime; avoid extended non-operational periods.
These guidelines represent best practice for installation; verify appropriateness for specific site conditions.
Handle units carefully to prevent damage. Ensure stability when lifting and use suitable webbing slings; avoid chains.
Consider discharge consent, planning approval, ground conditions, water table, soakaway tests, and access for servicing.
Design pipework to minimize damage from differential movement. Support excavation side walls if they won't maintain a vertical wall.
Dewater excavations where water table is high or flooding is likely. Use polythene sheeting to prevent cement wash-out.
Ensure uniform support to avoid point loads. Use water for ballasting during back-filling; maintain water level during concrete pour.
Provide adequate electrical supply complying with regulations. Select cable and overload protection based on table data.
Excavate for unit, surround, and bed. Lay concrete bed appropriate for site conditions, possibly with hard-core sub-base.
Place unit on bed, ensuring no voids. Check and ensure unit is level end-to-end and side-to-side within tolerances.
Haunch concrete around the base. Pour water into chambers to specified depth for back-filling.
Back-fill according to site conditions. 1250mm invert depth units require concrete back-fill to within 500mm of ground level.
Assemble anchor bars. Place concrete back-fill in 200mm increments, ensuring compaction and avoiding voids.
Fill tank with water simultaneously with backfill material to prevent flotation. Maintain water level within 200mm of concrete level.
Use pea shingle, sand, or other free-flowing granular material for back-filling up to outlet level.
Position control panel safely, not reachable from the unit. Installation by qualified electrician according to IEE regulations.
Set frame legs in concrete base, ensuring stability. Maintain clearance from finished ground level to the panel bottom.
Remove covers carefully. Feed power supply cables through glands and wire to terminal blocks as per guides.
Feed discharge pump power cable through gland hole and terminate to specified connections (TB1) following Table 2.
Feed sludge return pump cable through gland hole and terminate. Set run and pause times for the pump using Table 3.
Feed dosing pump and probe cables through glands and terminate to specified connections (TB4, TB7) following Table 2.
Set run and pause times for the chemical dosing pump using the switches as detailed in Table 4.
Feed alarm cable through gland hole and terminate to connections (TB5). Activate the alarm using switch 10.
Remove link, feed float cable through gland hole and terminate to connections (TB6). Fix float bracket correctly.
Mount beacon up to 30m from panel. Feed beacon cable through gland hole and terminate to connections (TB8).
Connect battery, check display for 'F1', turn on mains supply. Press reset button to clear display.
Recommend Pre-Service Agreement Inspection. Refer to Owner's Handbook for detailed start-up procedure.
Leave unit filled with water. Switch on motor and leave running, even without sewage feed.
If no power, remove and store motor/gearbox unit in a dry environment until ready for operation.
Do not connect integral pump units to sewage supply without ensuring electricity is connected and unit is operational.
